Family of fixation devices with variable taper

摘要

A family of devices attach elements previously bored in a cylindrical manner, wherein each device has a in extending along an axis and a tapered shaft and a head, and a bushing intended for accommodating the shaft of the pin, the bushing extending along the same axis having an outer cylindrical surface and an inner tapered surface. The family has at least two devices with bushings presenting, before installation by interference, an identical outer diameter and a different rate of taper of the inner surface.

主权项

1. A family of at least two subfamilies of devices for attaching a number of elements having cylindrical bores therethrough with the same diameter, each device of each subfamily comprising:
a pin extending along an axis and comprising a tapered shaft and a head, a bushing accommodating the shaft of the pin, the bushing extending along the same axis and having an outer cylindrical surface having an outer diameter and an inner tapered surface, wherein said at least two subfamilies of devices comprise bushings comprising, before installation by interference, identical outer diameters, and wherein the inner tapered surface of the bushing from one subfamily has a rate of taper different from the rate of taper of the bushing from another of the at least two subfamilies.
